Useful e.g. connecting RNNs and convnets.

Usage

layer_permute(object, dims, ...)

Arguments

object

Object to compose the layer with. A tensor, array, or sequential model.

dims

List of integers. Permutation pattern does not include the batch dimension. Indexing starts at 1. For instance, c(2, 1) permutes the first and second dimensions of the input.

...

For forward/backward compatability.

Value

The return value depends on the value provided for the first argument. If object is:

  • a keras_model_sequential(), then the layer is added to the sequential model (which is modified in place). To enable piping, the sequential model is also returned, invisibly.

  • a keras_input(), then the output tensor from calling layer(input) is returned.

  • NULL or missing, then a Layer instance is returned.

Input Shape

Arbitrary.

Output Shape

Same as the input shape, but with the dimensions re-ordered according to the specified pattern.

Examples

x <- layer_input(shape=c(10, 64))
y <- layer_permute(x, c(2, 1))
shape(y)

## shape(NA, 64, 10)
